For each Enabled Station that establishes a connection, SDLC creates
   a Port entity.

1  –  show

   show sdlc port

   The show sdlc port command displays the attributes for the SDLC
   Port subentity.  A Port subentity is created dynamically for each
   connection to a remote station.  Each Port is created when a
   connection is established and deleted when the connection is
   terminated.  Use the command show sdlc port * to display a listing
   of the existing Ports.

   Ex,  ncl> show sdlc port 1 all counters

1.1  –  Identifier

   Name            A unique value assigned to the Port by the SDLC
                   entity.  The value is an unsigned integer.

1.2  –  Status

   UID             Displays the entity's unique identifier, which
                   is generated when the Peer Server creates the entity.

   Station         Displays the name of the SDLC Link Station subentity
                   that the client specified in the connection request.

   Client          Displays the name of the client that connected to
                   this Port's Station.

   Role            Displays whether the station role is to be primary
                   or secondary when it becomes active.

   Address         Displays the address of the secondary station.

   Transfer        Displays the link-level transmit/receive capability
   Mode            for the connection, which is set to the transfer mode
                   characteristic of the SDLC Station. Might be altered
                   during XID negotiation.

   Modulo          Displays the Response Mode supported by the Station.
                   Normal Response Mode supports Send and Receive Window
                   Sizes of 1 to 7.  Normal Response Mode Extended
                   supports Send and Receive Window Sizes of 1 to 127.

   Send Window     Displays the negotiated maximum number of transmitted
   Size            I-frames that may be outstanding before the adjacent
                   station requires an acknowledgment response.  The
                   value is initialized as the SDLC Station window size
                   and might be reduced during preconnection XID
                   negotiation.

   Receive         Displays the negotiated maximum number
   Window Size     of received I-frames that may be outstanding
                   before this station requires an acknowledgment
                   response. The value is initialized as the SDLC
                   Station Window Size and might be reduced
                   during preconnection XID negotiation.

   Send Frame      Displays the negotiated maximum size of frames
   Size            (excluding header) sent by the connection.  This
                   value is initialized as the SDLC receive frame
                   size.  The value might be reduced during
                   preconnection XID negotiation.

   Receive         Displays the negotiated maximum size of frames
   Frame Size      (excluding header) received by the connection.
                   This value is initialized as the SDLC Station send
                   frame size.  The value might be reduced during
                   preconnection XID negotiation.
